SPECIFICATION forming part of Letters Patent No. 452,703, dated May 19, 1891.

Application filed March 25, 1890. Serial No. 345,256. (No model.)

To all whom t may concern: man is moved up and down it will impart a Be it known that I, IsHAn T. HARDY, of the vertical'reciprocation to the plunger, while at city of St. Louis,in t-he State of Missouri, have the'same time the plunger can be swung out invented a certain new and useful Improveof a vertical line or out of a line parallel with 55 ment in Tobacco-PackingMachines, of which the pitman for the purpose of cleaning it or the following is a full, clear, and exact defor the purpose of getting it from over the scription, reference being had to the accomhopper when desired, and when it is released panying drawings, forming part of this specithe spring will automatically move it back iication. into its vertical or working position. 6o 1o My invention relates to certain improve- 13 represents a crank on the end ofashaft ments in machines for automatically filling 14, journaled by meansl of suitable boxes sacks or bags with cut tobacco; and my invento the frame 2. This crank is provided with tion consists in features of novelty hereinafa wrist-pin 16, tting'in a slot 17 of a crosster fully described, and pointed ont in the head 18,permanently connected to the pitman 65 r 5 claims. 8, and above which the pitman extends to Fig. I is a side elevation of my improved and works through a guide 19 on the frame 2, machine, partly broken away. Fig. II is a deby which,in connection with the guide 2O atthc tail vertical section taken on line II II, Fig. lower end of the frame 2, the pitman is held I. Fig. III is a front elevation showing the and caused to move in a vertical plane. The 7o 2o plunger in its raised or upper position. Fig. slot 17 in the head 18 is made horizontal at, IV is a similar View showing the plunger in its ends, as shown in Figs. III and IV, while its lower position, and showing the sack-mold its central portion is made in the arc of a ciror the receiver and the filling tube or neck in ole, so that as the crank 13 is turned the pitsection. v man will be raised and lowered and willhave 75 Referring to the drawings, 1 represents a a nest or stop at the limit of each ofits movesuitable support, to which is secured a frame 2. ments, while the wrist-pin is traveling through 3 represents a table extending from the supthe portion of the slot 17 which is made in the port 1, and upon which rests a mold or sackarc of a circle,thus giving time while the pluni-l receiver 4, having acen tral opening, as shown ger is in its lower position forthe compressed 8o 3o in Fig. IV. Over the mold is arrangedahoptobacco to remain under the pressure for a per 5, having a tube or hollow neck 6 extendsufficient period of time to canse it to be firmly ing down a distance into the mold., as shown packed in the sack, and giving time for the in Fig. IV. hopper to be lifted, as hereinafter explained.

7 represents a plunger secured to the lower The shaft 14 is connected bya cog-wheel21 85 end of a pitman 8. A hinged connection is and a pinion 22 to apower-shaft23, journaled preferably made between the plunger and in extensions 2n of the frame 2. The shaft 23 pitman by forming ears 9 on the pitman, beis provided with a driving-pulley 21 to retween which the upper end of the plunger ceive a belt, by which motion is imparted to fits, and through which a connecting-bolt 10 the machine. The driving-pulley is loosely 9o 4o passes, the bolt also passing through the npmounted on the shaft 23, and is connected per end of the plunger. thereto automatically by means of a sliding 11 represents a spring coiled around the member 25 of a clutch, which is caused by extended ends of the bolt V10, and above andv having a feather-and-groove or other suitable below which it extends. The upper end of connection with the shaft (see Fig. II) to turn 95 the spring bears against the pitman 8 and therewith. Theinnerfaceof the sliding memthe lower end bears against the plunger 7. ber 25 is adapted to have frictional contact (See Figs. I, III, and IV.) The tendency of with the hub 2G on the pulley (see Fig. I) this spring is to hold the plunger in line with when it is moved over against the hub, and the pitman, the lower end of the pitman restthus causes the pulley to be turned with the '1 oo 5o ing on a shoulder 12 on the plunger. (See sliding member and withthe shaft. The slid- Fig. I.) It will thus be seen that as the piting member is moved by means of a suit-able lever 2T, pivoted at 2S to the frame i, thcupper end of the lever being bifureated, as shown in Fig. II, and provided with pins 29, fitting in an annular groove in the sliding member, so as not to interfere with the turning of the sliding member with the shaft while forming a connection between the lever and sliding member, which will cause the latter to be moved longitudinally on the shaft.

The lever 27 moved to bring the sliding member of the clutch into contact with the fixed member or hub 26 by means of a treadle 3U, a ben-crank lever 3l, and a connectingrod 32. The bell-crank leverll. is pivoted at 33 to the frame 2, with its upper end bearing against the lower end of the lever 27, while to its lower end the upper end of the rod 32` is connected. It will be seen that by applying pressure tothe outer end of the treadle 30 that the upper end of the bell-crank lever will be forced in the direction indicated by the airow, Fig I, causing the upper end of the lever 27 to be forced toward the pulley El, and consequently causing the sliding member of the clutch to be brought up against the hub 2G, causing the shaft 223 to be turned with the pulley, which is driven eontin uousl y, and causing also the shaft il: to be driven through means of the connecting-gears 21 22. On the shaft lt is permanently secured a disk St, having a notch or opening 35. (See Figs. I and II.) As the sliding member of the clutch is thrown into frietional contact with the hub 2G of the pulley 2st a pin or projection 3G on the lever 27 is disengaged from the notch 35 of the disk 3l, and as soon as the machine starts the prcssu re is removed from the treadlc 30, the sliding member of the clutch being held into contact with the hub 2G by the pin 36 riding on the face of the disk 3l until the pin 3G comes opposite the opening 35 of the disk 34, and then the lower end of the lever 27 is pulled by a spring 37 toward the disk, causing the pin to enter the opening 35 to stop the rotation of the shaft la, and at the same time the movable member of the clutch is carried out of contact with the hub 26, so that the rotation of the shaft 23 also ceases. The parts are so disposed that while the pin 36 is riding on the disk 34 the plunger 7 is making a complet-e movement from its upper position to its lower position and back again to its upper position, and when it has completed this movement it is automatically stopped or retained at its upper position until the treadle 30 is again operated to move the pin 3G outof engagement with the perforation 35 and the movable member of the clutch into engagement with the hub 26 of the pulley 2t. rlhe neck or tube of the hopper fits loosely in the mold 4, so as to be capable of movement therein. Before starting the machine a sack is placed on the mold beneath the tube or neck of the funnel and the tobacco is placed iu the funnel. The plunger then descends, forcing the sack into the mold and forcing the tobacco from the funnel into the sack, as shown in Fig. IV, the neck or tube of the funnel at the same time being forced a distance into the mold inside of the sack, so as to hold the sides of the sack taut while the tobacco is being compressed. Before the plunger commences to make its upward movement the funnel is raised to lift its tube or neck out of the mold by means of a vertical strip or plate 40, having adjustable horizontal arms 4l, which embrace the neck or tube of the funnel, and which bear beneath projections or lugs 42 on the funnel,as shown in Figs. I, III, and IV. The upper end of the strip or plate 40 is connected by means of rods 43 43 to a cross-head ai, located just over the shaft ist. The rods 43 43 are located on each side of the shaft lil, (a pair of them being on each side,) and to one pair i3 of these rods is journaled a rollera, against which at the proper time a cam t6 on the shaft la bears to lift the plate or strip 40, and consequently the neck of the funnel, out of the mold. The funnel being raised from the mold while the plunger is still in its lower position prevents the tobacco being raised from the sack bythe funnel, and after the funnel has made this upward movement the plunger recedes, and before the plunger descends again the cam 4G has left the roller 45, permitting the plate l0 and the funnel 5,with`its neck 6, to recede to their lower position, the filled sack having been removed and a fresh sack placed over the mold before the hopper recedes or is forced to its lower position.

I claim as my inventionl. 'lhe combination ot' a pitman formed with ears at the lower end, aplunger having a shoulder, the bolt by which the plunger is hinged to the ears of the pitman,and aspring coiled around the extended ends of the bolt and bearing on the pitman and on the plunger, substantially as described.

2. The combination of a fiame, a shaft journaled in the frame having a cam, a pit-- inan,meelianism connecting the pitman with the shaft, a plunger connected with the pitman, a hopper surrounding the plunger having projections, an upwardly-extending plate, arms secured to the plate for engaging the projections on the hopper, paired rods secured to the upper end of the plate, a pair being located on each side of the shaft, the cross-head secured to the rods over the shaft, and a rollerjournaled to one pair ot' the rods and on which the cam bears to lift the plate, substantially as described.
